Avengers: Endgame Encore’s commanding 96.1% market-implied probability stems from its robust opening day, which delivered $11.2 million from 3,060 screens and outpaced new wide releases. The reissue benefits from fresh post-credit sequences teasing Avengers: Doomsday, heightened MCU anticipation, and proven audience draw for the 2019 blockbuster. Newcomers such as A24’s Primetime and Paramount’s Heart of the Beast posted solid previews but trail in early tracking, while Resident Evil’s second-weekend hold appears insufficient to overtake. An upset would require dramatic word-of-mouth surges or underperformance by the Marvel title that shifts the final three-day totals, though current estimates project Endgame finishing comfortably ahead at roughly $23–26 million.
